Ground Stability Monitoring Using InSAR

During my tenure at the Geoinformatics Center, I was involved in a project focused on monitoring ground stability and supporting the reconstruction process in the Palu region of Indonesia, which was devastated by the massive earthquake in September 2018. The project, titled Support for Emergency Assistance on Rehabilitation and Reconstruction in Central Sulawesi, utilized Persistent Scatterer (PS)-InSAR technology based on Sentinel-1 data, processed through the Geohazard Exploitation Platform (GEP). This method provided detailed ground motion data, which I used to assess the stability of critical infrastructure, such as roads, buildings, and canals. The findings played a key role in ongoing monitoring and informed decisions for reconstruction efforts in the region.

Additionally, I participated as a resource person in the Earth Observation Services for Water and Food Security Planning in Indonesia training program in November 2021. This collaborative initiative, involving the European Space Agency (ESA), the Asian Development Bank (ADB), the National Research and Innovation Agency of Indonesia (BRIN), and the National Institute of Aeronautics and Space of Indonesia (LAPAN), aimed to promote the application of Earth observation science for water and food security planning. As part of this program, I had the privilege of leading a session on infrastructure stability mapping in Central Sulawesi, where I demonstrated how InSAR technology could be used to assess ground deformation and infrastructure stability in post-disaster environments, further supporting recovery and resilience planning.
